The device has been designed so that enraged drivers won't be able to smash it up or burn it down.

Standing 12ft, it can scan four lanes and snap cars from front or rear - with no visible flash to warn drivers they have been clocked.

Dutch firm Peek Traffic hopes to sell the machines, which cost up to £50,000 each, across Europe.
